To all wholmt't may concern.' i

Be it known that I, RALPH lV. BORCHERT,

ay citizen of the United States, residing at the city of St.: Louis and State of Missouri,

have invented a nevvl and useful Marine` Motor Attachment,` of which the following is a specification.

This invention relates to marine motor I attachments.

My invention is particularly `adapted-to Y support a motor in connection with the stern of a boat in a manner permitting the prol fpeller to be raised above the water to'enable the motor to be started more lrapidly and easily than could be done if the motor Aremained in the water.

My invention also includes a novel con-` struction by which the propellerl can be supported out of the Water when desired, as

When the boat is landing or passing over e Shoals or other submerged objects.

The invention also includes novel means byv which the propeller shaft can be held in vertical adjustment irrespective of the shape or angle ofinclination vof the stern board of the boat. i

An object of the invention is to provide an improved motor attachment for serving the functions above stated and others hereinafter mentioned.

Other objects of the invention will appear from the following description in which reference is made -to the drawing illustrating .the invention, and, in Which-- Figure 1 is a lside elevation of 4my 1m- `proved motor attachment.

Fig. 2 is a view looking toward the other side lfrom that shown in Fig. 1.

Fig. 3 is a detailed view illustrating 'the means by which the propeller is supported in any desired adjustment;

, Figs. 4 and 5 are detailed views illustrating the heating device for heating the gaso-v lene passing to the motor.

Fig. 6 is a detailed sectional view showing the switchdevice controlling the cir- Acuit of the ignition system of the engine.

The invention shown in Figs. 1 to 5 com- -prises means for supporting the motor in -a manner to permit the propeller to be raised manually out of the water for any desired purpose, and also to permit the provpeller to be raised, without injury thereto,

by contact of the motor support with any j fsubmerged object, or when the motor is-pass.

ing over Shoals. As shown, the motor is .ber 5 vis provided with ratchet teeth, as

shown. A bracket comprising a collar 7 and. a frame 8 is attached tothe sleeve 3. A pawl 9 is pivotally supported Within the frame 8 and is"v actuated downwardly into engagement with the ratchet teeth on the arms 5 by a spring 10. Thus the motor shaft may be supported vertically, irrespec-v tiveV of the angle of inclination lof the stern board of the boat. Furthermore, this construction permits the propeller to be raised entirely above the water which is a mattei' of considerable convenience in starting the motor, particularly in cold Weather. After the n'iotorhas been started and vthe engine has jbecome heated,- the propeller' may be easilydropp'ed into the water b Jroper control of the pawl 9` which ma; e-'l'engaged with the. members 5y at the proper place to hold the propeller shaft in vertical 'position.

The construction is also ofv advantagepbecause it permits the propellerl to be. lifted quickly, either by hand or automatically,

out of the water when passing over shoals,

or over submergedobjects by which the motor might be injured. The construction described also permits the propeller to `be supported out of the water when the boat is being towed, thus avoiding the resistance o the wateragainst the propeller. j

In addition to the advantages mentioned it will be observed by reference to Figs. 1

and 2, that the engine is.supported farther astern and does not project, so farover the boat as is the case with the motor attachments now in-use.

Each of theI arms 5 is formed witha Slot 11 through which abolt -12 extends, the said bolt bei g provided oI'r each end Witha' thu-mb nut 13 by' which the bolt maybe heldn any desired positiol l?! Which 1t is plaantA Said bolt is on the forward side of the ropeller shaft sleeve and serves as an L utvment for said sleeve to support said sleeve in any adjustn'ient in which it may be placed. Thus, said abutment will hold the propeller shaft in lproper position, even though the pawl 9 might become disengaged from the ratchetI teeth on the arms 5.

As shown in Fig. 2, my invention com-,-

prises means for opening the electric circuit as an incident to raising the propeller whether by contact with any submerged object or manual-ly. At this point attention is called to the fact that the arrangement is such that if the propeller support contacts with any submerged object the propeller will be raised thereby, this movement being permitted by the construction described, in

' which the pawl 9 is tree to slide or escape in one direction over the teeth on the arms 5. This prevents any damage or injury to the propeller or to the other motor mechanism. An electric switch 14: in the circuit to the ignition devices'otl the motor is ot' the Well known typ'e inwhieh there is apush button 15 which is pressed inwardly in the usual manner to close the switch. The well .known switch device sho-wn comprises a contact member 15?L in 'circuit with one of the wires 14a, andl a coperating member 15b in circuit with the other wire 14. The contact member 15b is in the form of a spring plate, the resiliency of which is exerted to move the plate 15b out of contact with the plate 15a' to open the circuit. When the push-button 15 is pressed inwardly, the contact member 15h is pressed into contact with the contact member 15a to close the circuit. 'A cam disk 16 isjattached to the pivot 6 Vsupporting the' motor. A wide portion of the cam disk is normally in contact with the push buttonv 15 'and holds the push button pressed inwardly to close the switch of the circuit. However, when the propeller is raised the push-button `15 enters a notch 17 in the disk. leaving the switch free to open in the usual manner. As a result of this operation the -motor is stopped as an" incident to raising -the propeller by contact with any submerged object, or otherwise. However, if the propeller be raised entirely out of the water the disk 16 again closes the switch, thereby closing the electric circuit and leaving the motor v free to operate` This is a great convenience in starting the motor. since it permits the propeller to 'be raised .entirely out of the water, thus avoiding the resistance of the water in the initial operation of starting thc motor,

The invention shown in F igs. 1V and 2 also comprises means Ifor heating the fuel passing to the motor. The heating device comprises a chamber. 18 inclosing` a number of j coils 19 in the pressage which conductsthe fuel from the fuel tank 2O to the motor. A

burner 21 in the chamber 18 heats the coils 19 so that the fuel passing to the engine is prime and heated.
